EMORY FARRAR, OF NEW YORK, N. Y.

TYPE MARKING-MACHINE.

SFECIFICATION forming part of Letters Patent No. 251,425, dated December27, 1881,

Application filed JullyliO, 1881. (Model.)

To all whomy 'it may concern:

Be it known that I, EMORY FARRAR, ot' New York,` in the county and Stateof New York, have discovered a certain new and useful Improvement inType l\Iarking-l\/Iachines, of which the following is a full, clear,concise, and exact description.

My invention relates to type marking-machines or stamps, in which thetype are carried upon wheels; and it consists in the combinations ofparts hereinafter set forth.

Figure l is a side elevation, and Fig. 2 is a view from below, of mytype-marker. Figs. 3, 4, 5, and 6 are details of portions thereof.

Like parts are indicated by similar letters of reference.

The frame D is provided with short arms pr0- jecting at right anglesfrom its sides. The outerends ofthe arms are bored out and tapped toreceive wrist-pins. The typewheels A B C turn upon these pins inparallel planes. Adjustable roller-guides E F are attached to the frame,as shown. The Wheels A and B diier only indiameter, and are shown indetail in Fig. 3, in which t is the helical spring, a side view of whichis shown in Fig. 6, attached t0 the frame and to the inner disk, b, ofthe wheel, as shown at b'. The wheel is run over the inkpad or surfaceto be marked against the tension of this spring, and is brought backautomatically to its normal position by its recoil.

c is the outer disk ofthe wheel, and e is the rim, which affords asupport for the type. The rim e may be first placed about the disk e',and then soldered to disk b. The edges of the outer disk, c, and theinner disk, b, project inwardly, as shown at poiutsf g. The projectingedge g of disk c should be removed for a short distance, as shown at h,so that the type may be entered. The projecting edges f g fit thegrooves provided in the type, which may be entered one at a time, andcrowded along until the first one entered comes against the stop, whichmay be attached rigidlyto the rim '6. A stop, i, is shown on wheel B,Fig. 2.

After the type are entered xthe clamp k is brought against the last oneentered. The clamp is held by means ofthe thumb-screw l. `The disk emoves independently, and the p0rtion h may thus be brought to anyposition in respect to the clamp and stop. When the thumb-screw l istightened the disk is held firmly in position.

Wheel C is divided through the center of the rim M, as shown in Fig. 2.rlhe slot n (see Fig. l) is provided in the wheel C, instead of simplyremoving a portion of the projecting edge, as shown at h, Fig. 3. Thisslot l find the more convenient form ot opening. 'The type are enteredor set one at a time in wheel C, and crowded around till arrested by astop provided on the rim m. This stop is not shown in the drawings. Itis similar to stop t', and is attached to one side only of the rim m.The type are held in place by means of the clamp o. (See Fig. 4.) Thecatch p (shown by dot# ted lines) is pivoted to clamp o at point q. Thespring r normally holds this catch or stop p in the position shown, sothat its upper end comes against the under side ot' the rim m. The clampois thus held in position. By pulling back on the catch or stop pagainst the tension of spring r, the catch or stop isv turned on thepivot and the clamp is released. The clamp is designed to hold the typein position when placed upon the Wheel.

The outer and inner disks of wheel C are held together by means ot' athumb-screw, s.

The counterbalance-weight s', Fig. 2, may be used instead of the helicalspring to bring the wheel back to position alter it has been used.

I place a spiral spring between the outer and inner disks of wheel C,around the hub. This spring tends to hold the two disks apart. By meansot' the thumb-screw the wheel may be adjusted to type of any size.

When the type are very small washers may be used.

In Fig. tail.

The leg t is pivoted to the frame, and held by spiral spring a againstthe stop o.

IVhile inking a wheel the supporting-wheel may be swung forward bypressing the thumb upon the, wire w.

p The wheel w is held, as shown, by sleeve y, which may be adjusted atany height upon the leg by means ofthe set-screw z.

The type I nd most desirable are of rubber fastened to a metallic base,preferably of brass.

5 adjustable guide E is shown in de- Having thus described my invention,what I Y claim as new. and desire to secure by Letters Patent, is-

1. The frame D, provided with parallel wristpins for the wheels, incombination with guides E and F, and screws for adjusting the sleeves tothe legs, and springs and levers, onespring and oneleverforeach guide,whereby the guides may be held up while the wheels are passing over theink-pad, substantially as and for the purpose specied.

2. The fra-ine D, provided With three parallel wrist-pins for theWheels, two of said wristpins being on different sides of the widenedportion of the frame, one higher than the other, so that only one of thewheels A C at the saine time may touch the surface to be marked, theother Wrist-pin being at the bent extremity of said frame, whereby theplane of wheel B is brought about midway between the planes of 2o thesaid wheels A and C'.

3. The combination of frame D, type-wheel C, guide-Wheel E, spring u',lever w, and stop QJ, as and for the purpose specified.

In Witness whereotl I hereby subscribe my 25 name in the presence of twosubscribing witnesses.
